About the Course

Do you realize that the only functionality of a web application that the user directly interacts with is through the web page? Implement it poorly and, to the user, the server-side becomes irrelevant! Today’s user expects a lot out of the web page: it has to load fast, expose the desired service, and be comfortable to view on all devices: from a desktop computers to tablets and mobile phones. In this course, we will learn the basic tools that every web page coder needs to know. We will start from the ground up by learning how to implement modern web pages with HTML and CSS. We will then advance to learning how to code our pages such that its components rearrange and resize themselves automatically based on the size of the user’s screen. You’ll be able to code up a web page that will be just as useful on a mobile phone as on a desktop computer. No “pinch and zoom” required! Last but certainly not least, we will get a thorough introduction to the most ubiquitous, popular, and incredibly powerful language of the web: Javascript. Using Javascript, you will be able to build a fully functional web application that utilizes Ajax to expose server-side functionality and data to the end user....

An excellent course for beginners. 5th week was a bit rushed i.e JSON,Ajax and jquery. So i had a really hard time getting grasp of them and took a star out of my review. Otherwise wonderful tutor.

I went into this course with no previous experience in programming. Overall, I would say it was a very helpful introduction to the subject, especially the HTML and CSS modules. I feel like I got a general understanding of how these two programming languages work and how to utilize them to build a simple website. The lectures were straightforward and interesting and the assigments were helpful, hands-on practice that gave a sense of accomplishment.

The last two modules, which covered JavaScript, definitely got more convoluted and more difficult to follow. The Javascript assignments were fairly simple and yet didn't leave me feeling like I had much understanding of what I'd really done to complete them. I think this part of the course material could have been explained better or in more depth.

My other criticism of this course, as also stated byb many other reviews, is how outdated it is. It took a lot of extra time to set up for the first assignment because a lot of things with GitHub and the various software has changed. However, I would not let this dissuade you from taking the course, I actually think doing some of my own research and figuring things out was helpful in getting things to stick in my brain. There are a lot of people with similar questions so you can usually find answers in the discussion forum or on sites like Stack Exchange, just be aware of the extra time needed to complete assignments. I hope that Johns Hopkins University will update this course soon to make it a bit more useful for current times.

Sorry in advance for my english.

Pros - Theory, presentation, organization. In general, the course is delivered very well, it is interesting to watch, the lectures themselves are delivered beautifully and informatively. A trip to a client is a very interesting move. Instructions for the tasks and in general all the material (main and additional) is very useful and well structured.

Cons - Partly material, tasks, difficulty level of some topics. Outdated technologies are used (which is actually logical, after all, the course is old, but during this time it has not undergone changes in accordance with the development of technologies), mostly bootstrap, but there are also many small points that are no relevant and teach bad code (iife). Tests that I would like to replace with tasks. Tasks that are too simple and few of them. There is also a problem with a jumping level of complexity and missing explanations to the code. It will be quite difficult for a beginner to master this course.

In general, I recommend the course for educational purposes with the possibility of skipping part of the content.

I think this course fulfills its purpose in providing a comprehensive introduction to the three basic web development components, and showing the ways they are implemented through a real project. The problem is that, from what I can tell, this course is almost 5 years old and there doesn't seem to be any kind of update or revision, many times I got errors or bugs in my test code while following the lectures, with no way of telling if I did something wrong or something changed in the implementation. Also, the coding assignments felt way too simple for the amount of content that was presented in each module, even without having a good grasp of the concepts it's easy to get a 100 since the comments basically hold your hand through the code.

In general, for someone like me who had basic knowledge of HTML and no prior experience with CSS and Javascript, I got what I expected and I feel much more confident in learning more about web development, but the course definitely shows its age, so there may be better options nowadays.

This course was great in terms of material composition and the lecturer! I learned a lot and will definitely recommend it to others. I'm also taking the AngularJS course, because I really liked this one!

On the down side: in my opinion, the assignments (especially week 3 & 4) could be more challenging, as the course is targetted at web developers, so people familiar with coding. I found them quite easy. I understand that the last assignment was aimed mostly at forcing students to view all the lectures or get familiar with the provided code, but doing something bigger for the assignment (or at least without such obvious hints) would be a nice challenge and bring more value to the certificate, I think.

Splitting week 4 into two with separate assignments is also worth considering, as there was a lot of material covered in the last week, in my opinion (but I may be biased, as I went through the last week in a hurry, because I was late with my assignment).

Cons: 'let' and 'const', which are important concepts of JavaScript haven't been discussed. Differennce between window and global isn't discussed but used interchangeably. Assignments of module 4 and 5 are most of the part easy, they could be made a bit harder. I felt that Ajax code could be made easier to understand. I gave extra 3x time just to understand the Ajax from other sources and then the ajax code present here.

Pros: Apart from all the cons mentioned above it is nevertheless a recommended front-end web development course for beginners. You will learn HTML, CSS, bootstrap, git(hub), JavaScript, ajax, http, a bit of jQuery, DOM, etc. Just an advice to the students: don't be afraid of using external resources to understand the concepts better, specially Ajax, document, window/global, Http requests, rest API and jQuery. w3schools and MDN are the go-to sites for this course.

I have already undertaken a primer course like this through Coursera but found this one to go into more of the specific terminologies and concepts at a granular level. I thought overall the pacing was good and the application to a real world application in the form of a restaurant website was helpful in grounding the concepts. I have marked the course down a star because some of the information relating to Bootstrap is now very much out of date. There are a number of elements that no longer function the same as the Bootstrap framework has moved on quite a bit (4.5 at time of writing) and this course has not been updated to account for those changes. I found the odd piece of javascript didn't function quite as it should as well, also probably due to the age of this course. I found the Week 5 module quite difficult but would say I've learned a lot from this course.

HTML & CSS were very well taught. But JS -- especially week 5 - not very well taught - confusing. Yaakov said in the video that you need basic programming knowledge before learning JS, although I was under the impression that this was a beginners course. I even had a little JS background before this course but understanding AJAX/Week5 would be easier if it was less rushed. For JS especially, I also think that assignments & practice quizzes could've been more frequent. I wish JS was taught better. The course is also outdated. I was so confused with Github, and I think I finally understood it better in week 5, haha, just by luck/repetition. Regardless, I did learn more about HTML/CSS and JS. So taking this course was helpful. Thanks for a relatively good course!
